Notes on the Hermle 351 and 350 series

The Hermle 351 and 350 series is a spring driven westminster chime unit that takes a size #8 key. This is a square shaped movement with the movement plate size of 120 x 120mm. The 351-8** series is a two spring and one weight cable unit.

What is being offered on this page is the movement only with out the pendulum, gong or dial. These movement come as the movement itself with its hand nut and if a pendulum unit, comes with the suspension spring and leader.

You will need to match up your CM length from the back plate of your old unit to the new one. The options indicated all that is available by stock. If there is a CM number you need but is not listed we can still create it most likely by changing some gears. If this is the situation please just give us a call 800 381 7458.

What Happened to the old movement?Other Names UsedHow to orderHermle Movement AvailabilityWhy order a new clock movement?

With age, the mechanical clock movements oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost hundreds, if not over, a thousand dollars and in some cases it can take weeks or months to complete it.

Hermle Number Examples

Below are some typical examples of the Hermle clock movement numbering system. If your clock numbers are similar to this, its made by Hermle.

451-050 94cm

340-020

140-070

451-030 66cm

341-020 45cm

1151-050 114cm

451-053 94cm

1161-853 114cm

141-070 45cm

351-050 55cm

1161-850 94cm

241-070 94cm

When you have the numbers off of the back plate of the Hermle mechanical clock movement, you only need to match it up and order right on this website. The movement numbers are everything, if we provide a picture for that number and it does not look identical, it is still the correct movement as long as the numbers match up.

To get to the page that the numbers can be matched, the first thing to do is to match the movements number's prefix. The numbers prefix is the first set of numbers in the set, such as if the movement's numbers are 1161-853 114cm, the prefix would be 1161. You would go to the list of movements prefix's below and click on the 1161 to see all the movements in that number series, such as 1161-050 or 1161-853 or 1161-850.

The availability, at this time, is excellent. We stock all Hermle Clock Movements, with very few exceptions. Some special CM lengths may be a special order.

If it's not on the charts then it most likely will have to be made up special for an extra $30. This is a special order so please call it in.

Hermle is one of the biggest movement producers in the world today. Not only do they have the most movements being made, but they also have the best part availability when you need a component such as a pendulum or a dial, or a complete clock kit.

A Hermle Clock Movement generally lasts 25 to as much as 40 years. We usually get calls to replace units that were built in the early 80's or late 70's.

If you look at the back plate of the movement, you will see a couple of numbers above all the other numbers. You will see a number such as a 77 or an 83 or so on. This is the date the movement was built.

Replacing these units rather than getting them cleaned and oiled is usually the smart way to go as it has been factory improved, brand new, factory lubricated, easy to install, and it will cost less than a cleaning. Keep in mind however, that there are different grades of the same movement number. Some are cheaper, but they contain plastic parts.

The Hermle units that we offer here at Clockworks are the best grade available with no plastic components for a very reasonable price. The movement number has three or four numbers, then a dash, and some more numbers, then a CM length underneath it if there is a pendulum.

They are all consistent as they always have the numbers, then a dash, then more numbers. Basically if there is a dash in the movement number, and it's all numbers in the beginning with no letters like "A", it's a Hermle unit for sure. If there is an A before the number then it can still be a Hermle, but with the Seth Thomas name and numbering system.

On the back plate of the clock movement you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if the clock is weight driven or spring driven, if it has a pendulum, the size of the movement and the length of the hand shaft and much more. To match up the numbers to the new movement numbers is to get the exact same movement you have now but brand new. Since the new movement will be the exact same and not some knock off imitation, all of your existing clock components will usually fit just the same as the old unit.

A new mechanical clock movement can ship from USA the same day you order it, so the time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement, so all clock components will fit on to the new movement. The cost of a new movement is usually the same if not less than a cleaning on the old unit, and when it's installed it should last another 25-30 years without thinking about replacing or servicing it again. Some new units have bronzed bushings in key wear areas to increase the life of the movement, and on the non-pendulum units the balance has been improved upon for longer life and ease of timing. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Date Code Explanations

Hermle clock movement date codes are explained in this section. This is so you know when the movement was made and decide if the clock has lifed its life and its time for a new one. After figuring out the date code, figure out how old it is so you can justify the purchase of a new one with ease. If your clock is over 20 years old, replace it. If the clock is under 20 years old, consider fixing it instead.

Early movements prior to the year 1987 have just the stamp of the year on the back of the clock movement, 81 just means 1981.

From 1987 on, they used letter codes instead of numbers to represent the year made. Such as the year 1987 is only marked with the letter A instead, and 1988 is the letter B.

Letter Code Definitions

This section explains the letters that sometimes come after the movement numbers on a Hermle clock movement.

These letters often can be ignored in replacing a movement with us, we offer movements by the features instead. The letters on the new movement may or may not be the same on the new one, but you need not concern yourself with this. The features of the movement would be the same, such as if you had a second bit before and the movement number did not have an S, but the new one does have an S.
